2 Important Notes
This section includes an overall summary of the most important safety
requirements and notes that are mentioned in each individual section. To protect
your health and prevent damage to devices as well, it is imperative to read and
carefully follow the safety guidelines.
2.1 Legal Bases
2.1.1 Subject to Changes
WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any
alterations or modifications. WAGO Kontakttechnik GmbH & Co. KG owns all
rights arising from the granting of patents or from the legal protection of utility
patents. Third-party products are always mentioned without any reference to
patent rights. Thus, the existence of such rights cannot be excluded.
2.1.2 Personnel Qualification
All sequences implemented on Series 852 devices may only be carried out by
electrical specialists with sufficient knowledge in automation. The specialists must
be familiar with the current norms and guidelines for the devices and automated
environments.
All changes to the controller should always be carried out by qualified personnel
with sufficient sufficient skills in PLC programming.
2.1.3 Proper Use of the Industrial Switches
The device is designed for the IP30 protection class. It is protected against the
insertion of solid items and solid impurities up to 2.5 mm in diameter, but not
against water penetration. Unless otherwise specified, the device must not be
operated in wet and dusty environments.

2.1.4 Technical Condition of Specified Devices
The devices to be supplied ex works are equipped with hardware and software
configurations, which meet the individual application requirements. These
modules contain no parts that can be serviced or repaired by the user. The
following actions will result in the exclusion of liability on the part of WAGO
Kontakttechnik GmbH & Co. KG:
• Repairs,
• Changes to the hardware or software that are not described in the
operating instructions,
• Improper use of the components.
Further details are given in the contractual agreements. Please send your
request for modified and new hardware or software configurations directly to
WAGO Kontakttechnik GmbH & Co. KG.
2.1.5 Standards and Regulations for Operating the Industrial
Switches
Please observe the standards and regulations that are relevant to installation:
• The data and power lines must be connected and installed in compliance
with the standards to avoid failures on your installation and eliminate any
danger to personnel.
• For installation, startup, maintenance and repair, please observe the
accident prevention regulations of your machine (e.g., DGUV Regulation
“Electrical Installations and Equipment”).
• Emergency stop functions and equipment must not be deactivated or
otherwise made ineffective. See relevant standards (e.g., EN 418).
• Your installation must be equipped in accordance to the EMC guidelines so
electromagnetic interferences can be eliminated.
• Please observe the safety measures against electrostatic discharge
according to EN 61340-5-1/-3. When handling the modules, ensure that
environmental factors (persons, workplace and packing) are well grounded.
• The relevant valid and applicable standards and guidelines regarding the
installation of switch cabinets must be observed.

2.2 Safety Advice (Precautions)
For installing and operating purposes of the relevant device to your system the
following safety precautions shall be observed:
Do not work on devices while energized!
All power sources to the device shall be switched off prior to performing any
installation, repair or maintenance work.
Only install in appropriate housings, cabinets or electrical operation
rooms!
WAGO's 852 Series ETHERNET Switches are considered exposed operating
components. Therefore, only install these switches in lockable housings, cabinets
or electrical operation rooms. Access must be limited to authorized, qualified staff
having the appropriate key or tool.
Ensure a standard connection!
To minimize any hazardous situations resulting in personal injury or to avoid
failures in your system, the data and power supply lines shall be installed
according to standards, with careful attention given to ensuring the correct
terminal assignment. Always adhere to the EMC directives applicable to your
application.
Do not use in telecommunication circuits!
Only use devices equipped with ETHERNET or RJ-45 connectors in LANs.
Never connect these devices with telecommunication networks.
Replace defective or damaged devices!
Replace defective or damaged device/module (e.g., in the event of deformed
contacts).

Manual
Version 1.5.0
Protect the components against materials having seeping and insulating
properties!
The components are not resistant to materials having seeping and insulating
properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for
handling devices/modules.
Clean only with permitted materials!
Clean housing and soiled contacts with propanol.
Do not use any contact spray!
Do not use any contact spray. The spray may impair contact area functionality in
connection with contamination.
Do not reverse the polarity of connection lines!
Avoid reverse polarity of data and power supply lines, as this may damage the
devices involved.
Avoid electrostatic discharge!
The devices are equipped with electronic components that may be destroyed by
electrostatic discharge when touched. Please observe the safety precautions
against electrostatic discharge per DIN EN 61340-5-1/-3. When handling the
devices, please ensure that environmental factors (personnel, work space and
packaging) are properly grounded.
Laser radiation warning!
Do not stare into openings of the connections when no cable is connected, so as
not to expose the radiation.
It can emit invisible radiation.
It concerns here a laser class 1 according EN 60825-1.

2.3 Special Use Conditions for ETHERNET Devices
If not otherwise specified, ETHERNET devices are intended for use on local
networks. Please note the following when using ETHERNET devices in your
system:
• Do not connect control components and control networks directly to an
open network such as the Internet or an office network. WAGO
recommends putting control components and control networks behind a
firewall.
• Limit physical and electronic access to all automation components to
authorized personnel only.
• Change the default passwords before first use! This will reduce the risk of
unauthorized access to your system.
• Regularly change the passwords used! This will reduce the risk of
unauthorized access to your system.
• If remote access to control components and control networks is required,
use a Virtual Private Network (VPN).
• Regularly perform threat analyses. You can check whether the measures
taken meet your security requirements.
• Use “defense-in-depth” mechanisms in your system's security configuration
to restrict the access to and control of individual products and networks.
